Conservatives release video of police searching Damian Green's office

The Conservatives have just released some video of the police searching Damian Green's office in the House of Commons. The footage doesn't amount to very much. It shows Andrew Mackay, David Cameron's senior parliamentary adviser, challenging the police in Green's office (and, apparently, beating a pretty swift retreat when they ask him to turn the camera off) and most of the clip shows Dominic Grieve, the shadow home secretary, talking about the affair.

Grieve says the pictures show "a dark day for democracy". He's been accused of going over the top. Still, on the day before MPs slam the door on Black Rod before the Queen's Speech in memory of what happened when King Charles I sent the heavies into the Commons chamber, the release of this video is going to turn the temperature up even higher.
